Sometimes a suggestion for "saving" the posts that you've missed is to scroll up and screenshot it quickly so the incoming posts won't constantly make you look back to the very bottom of the chat box. I've always done so to keep up if I ever roleplay (which isn't often), yet I agree with the idea that the scrolling bar on the chat box should be edited in some way to be "easier" to use.
Thanks for sharing your ideas, floof!
To prevent me from being bumped down to the bottom of the chat box, I just hold on to the scroll bar on the chat box as I read and if I have to quickly read the post below/find a great then I screenshot the post I was looking for. As for the problem with finding the post, making the chat box taller seems to help a bit. But I have ran into the problem where I had to carefully scan the chat for just one post after I had been afk for a quite some time, even when I used those two techniques of searching the chat.
And in my opinion, I'm not quite sure about the change, being a compulsive screenshotter who screenshots every interesting message in the chat. The posts disappearing at the top of the chat window could mean that if I go afk for too long then I could miss some interesting posts in the chat(I sometimes go afk for hours).
Others could have a problem where they forget and/or miss a rp post that explained a change in the rules and so they end up telling off those who follow the new rules that were described in that missed post.
